I have a patch for gas (made to the version released with
binutils-2.5.2) which displays a warning when an Org fails (due to trying
to org backwards).
I am unfamiliar with patch submission protocol, but the patch follows
for those who are interested:
FILE: write.c
FUNCTION: cvt_frag_to_fill
ORIGINAL CODE:
case rs_org:
#ifdef HANDLE_ALIGN
HANDLE_ALIGN (fragP);
#endif
fragP->fr_type = rs_fill;
know (fragP->fr_next != NULL);
PATCHED CODE:
case rs_org:
#ifdef HANDLE_ALIGN
HANDLE_ALIGN (fragP);
#endif
know (fragP->fr_next != NULL);
if ( fragP->fr_type == rs_org)
{
if ( fragP->fr_offset < fragP->fr_next->fr_address)
as_warn ("Org failed! Org address changed from 0x%08X to 0x%08X\n",
fragP->fr_offset, fragP->fr_next->fr_address);
}
fragP->fr_type = rs_fill;
